Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-4533-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 453 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical footprint compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Automotive AEC-Q200 rating (application requirement)
• RoHS3 compliance (regulatory requirement)
• Moisture Sensitivity Level 1 (handling and storage compatibility)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter (lower) than ±0.25%
• Power Rating: Can be equal to or higher than 0.125W
• Temperature Coefficient: Must remain ±10ppm/°C
• Operating Temperature Range: Can be equal to or wider than -55°C ~ 155°C

All substitute parts listed maintain the mandatory parameters while offering improvements in tolerance specification or power rating capability. These substitutes are classified as active products with current manufacturing status and inventory availability.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The three Susumu RG series alternatives—RG2012N-4533-B-T5, RG2012N-4533-W-T1, and RG2012N-4533-W-T5—provide direct functional equivalence with improved tolerance specifications. All three maintain identical mechanical footprint, power rating, and thermal characteristics. The RG2012N-4533-B-T5 offers ±0.1% tolerance, while both RG2012N-4533-W-T1 and RG2012N-4533-W-T5 provide ±0.05% tolerance. These components are active products with established manufacturing and supply chain continuity. Selection among these three depends on tolerance requirements of the specific application circuit.

Alternative Substitute (Vishay Dale TNPW Series):

The TNPW0805453KBYEA from Vishay Dale provides an alternative from a different manufacturer while maintaining AEC-Q200 automotive qualification and ROHS3 compliance. This component offers enhanced power rating capability at 0.26W compared to the 0.125W rating of the original part, and extends the operating temperature range to 175°C. The tolerance specification is ±0.1%. This option is suitable for applications requiring higher thermal margin or extended temperature operation within the automotive specification envelope.

All substitute parts are active products with current inventory availability and maintain full compliance with automotive and environmental regulations applicable to the original component.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-4533-B-T5 be used as a direct replacement for RG2012N-4533-C-T5?

A: Yes. The RG2012N-4533-B-T5 maintains identical resistance value, package, power rating, and thermal characteristics. The tolerance is improved from ±0.25% to ±0.1%, which is a tighter specification that does not create compatibility issues. Both components are thin film, AEC-Q200 qualified, and ROHS3 compliant.

Q: What is the difference between RG2012N-4533-W-T1 and RG2012N-4533-W-T5?

A: Both components have identical electrical specifications: 453 kOhms ±0.05% tolerance, 0.125W power rating, and ±10ppm/°C temperature coefficient. The difference is in packaging format. The T1 designation indicates one packaging configuration while T5 indicates another. Both are supplied in Tape & Reel format and are functionally equivalent for circuit applications.

Q: Why does TNPW0805453KBYEA have a higher power rating of 0.26W?

A: The TNPW0805453KBYEA is manufactured by Vishay Dale using their TNPW e3 series platform, which incorporates design features that enable higher power dissipation capability in the same 0805 package size. This higher rating provides additional thermal margin in applications but does not affect the nominal resistance or tolerance specifications.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification and anti-sulfur construction. All are ROHS3 compliant and have Moisture Sensitivity Level 1 rating, meeting automotive supply chain and environmental requirements.

Q: Can I use TNPW0805453KBYEA in place of the Susumu parts?

A: Yes. The TNPW0805453KBYEA is electrically and mechanically compatible. It maintains the same 453 kOhms resistance, 0805 package, AEC-Q200 rating, and ROHS3 compliance. The component is from a different manufacturer (Vishay Dale) but meets all functional requirements. The extended operating temperature range to 175°C and higher power rating provide additional design margin.

Q: What is the significance of the obsolete status of RG2012N-4533-C-T5?

A: Obsolete status indicates that Susumu has discontinued manufacturing of this specific part number. Active substitute parts ensure continued availability for new production builds and field replacements. All listed substitutes are active products with current manufacturing and established supply chain availability.

Q: Do all parts have the same physical dimensions?

A: All parts use the 0805 (2012 Metric) package with identical length and width of 0.079" L x 0.049" W (2.00mm x 1.25mm). The TNPW0805453KBYEA has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the Susumu parts. This minimal difference does not affect PCB layout compatibility or component placement.
